The invention consists in the constriw tion, combination and arrangement of (le vices hereinafter described and claimed.

In the accompanying drawings, Figure i is an elevation oi several links and a chain constructed in accordance with my inven tion. Fig; 2 a pian of the same. Fig. ii is a sectional view of the same on the plane iniliratcrl my the line a z of 1. Fi iis a transverse sectional view of the same on the plane in rated 5y the line 0 1, of Fig. 1. Fig. 53 a detail perspertim of one member of one of the l nks.

In the embodiment of the ins ntio shown each iink i oi my iinpro'ierl e1 provide-ii with a narrmved end 2 anti a riding a pair of apart as at 5, the sni-ti spares 5, sin tween the walls 4 h ng adapted t-t the narrowed enrl of the in l link, so that the iinlis of the :hain ranged in partial orerlappin" J The walls "1- have rounded come 5" at their outer ends anrl present flanges 7 at their nor ends which are shaped to uniform the opposing ends of the wnils it of th next adjacent link.

Each link is here shown as comprising a pair of members 8, separable from the link 9 which extends longitudinally through the center of the narrowed cml 2 and the said members are secured together as by means 01" pins or rivets 10.

The narrowed end 2 of each link has a longitudinal slot 11 and is formed at the ii'illing A 86 :nasle in the fornr proportion and construction or ilu ral p without. departing ion and Within incline ahutinents of said narrowed emi being arrangei'i in the 53011.; of the spaced walls of the next adjarr t ii the abutiTlCHiS of the several its e: prising op -ng rounded eoinex surfaces forming ion rollin pivstzii connection between the lie 7 3. 1 chain '7 each having vex surfaces forming anti-friction rolling and pivotal connection between the links, each of said links comprising a pair of longitudinal separable members and the two members of each link being secured together.
